To all whom t may concer/n:

Be it known that I, EDWIN IV. IVEBB, citi- Zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Side Bearings; and I do hereby declare the following to be a full,

clear, and exact description of the invention,

` such as will enable others skilledin the art to which it appertains to make and use the same. Y

My invention relates to side bearings for cars of the type employing rockers interposed between the truck and body holsters,

and has for its object to provide a highly efficient and simple spring-centering device therefor. i

To the above end, the invention consists of rthe novel devices and combinations of devices hereinafter described and defined inl the claims. i' In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings :n Figure 1 is a view principally y 'tered Fig. 2 is a view corresponding to Fig. 1, V

with the exception that the rockers and spring-centering device have been moved to one Vextreme position; n A Fig. 3 is a view in transverse section taken `on the line 3 3 of Fig. 1;

Fig. 4 is a bottom plan view;

Fig. 5 is aview partly in plan `and partly in horizontal section-taken'on the line 5 5 of Fiel;

Fig.6 is perspective view of one ofthe Y rockers and Fig.Y '7 isa perspective view ofronev .of the followers.

. The numerals 8 and 9 indicate, respec-V tively, the body bolster and the truck bolster of a railway car. l i

The improved side bearing is carried by the bolster body 8 and, as shown, includes a cast rectangular housing 10 made'up of upper Vand lower sections. detachably connected by nutequipped bolts 11. Formed with the upper section of the housing 10 are y perforated flanges 12, through which may be inserted rivets or othery fastening means, not shown, to rigidly secure the side bearing to the body bolster 8. The lower section of which afford a in longitudinal central section, with the rockers cenently appear. Y

mediate portions thereof, are formed outwardly extended'recesses 16, the bottoms of pair of yopposite guide flanges or rails .17. The side walls of `these recesses 16 vafford stops 18. A bearing plate 19Vis secured to the top ofthe truck bolster 9.

per

Interposed between the bearingY plates 14 and 19, is a pair of rockers 20 located the one in advance ofthe other. are provided with apertures 21, 'which are alin'ed in'the direction of the, rocking movement of said rockers. Cast with eachfrockerv- 2 0 is a steel pin 22,- which extends vtransverselythrough the respective aperturev 21. Formed with the rockers 20, within the apertures'21 and at the ends of the pins 22, are two flat faces or surfaces 24, which ex- I tend both above and below said pins.

Supportedon the guide Vflanges 17 is a pair of followers 25, which extend between the rockers 20. The ends of the followers 25 areextended toward each other at 26 to l afford a longer bearing surface of said followers and the guide flanges 17 and; thereby hold said -followers 'in upright positions. At` the intermediate-portions of each follower These rockers ,20.

l25`is' a hub27, in which is formed an openV Y seat 28 that extends completely through said follower. OILthe outer faces of the followers 25, at the seats 28, are flat bearing faces 29, which normally engage the faces 24 on the rockers 20, for apurpose that will pres- .Loosely supported in theseats 28., with freedom for a limited endwise movement, is

iooV

a link 30 having at its ends hooks 31 in which rest the pins *22, thereby connectingv the two rockers 20 with freedom for rocking movement. Acoiled spring 32 encirclesthe lhubs 27 and link 30, re-acts against thefollowers 25 and normally and yieldingly holds the same 'with their surfaces 29 pressed d against the inner surfaces 24 of the rockers 50 f tween the, pins 22 and the hooks 81, whenV 20.y When the followers 25 are thus engaging the rockers 20, the ends of said followers are held'by the spring 32 against the stops 18, as best shown in Fig. 5. Byextending the coperating surfaces 24 and 29 both above and below the axis of the spring 32,

the rockers 2O are yieldingly but firmly held '.centeredV in upright positions, as shown in Fig. 1.

When the truck and body bolsters are `,moved to carry the rockers w into an exltreme position, as shownin Fig. 2, the right- "hand follower remains in engagement with the righthand stops 18, and the left-` 'hand follower 25Vis moved toward the'rightv "hand follower "25 by the movementof the Y left-hand rocker 20. This movement of the Vleft-hand rocker 2O causes thelower horizontal edges of its inner flat surfaces 24 to swing to the right on the arc of a circle and forces the engaged follower 25 to the right V and thereby com-presses the spring 32.

case the truck and body holsters swing back Y to their normal positions, without the body bolster liftingr sufficiently to carry the rock-V ers 20 out ofenfraoement with said truck bolster, the rockersv20 and centering device therefor will againassume their normal positions.

But, incase the body bolster 8 should lift, whenthe rockers 20 are yin a`t position as shown in Fig.` 2, sulciently to carry the rockers 20 out ofl engagement with i the bearing plate 19, the spring 32,'regacting will move the left-hand follower back to its normal positionagainstthevleft-hand stop 1 18 and, at thensaine time, centertheleft- Y* hand rocker 2O under the actionofvthe cooperating surfaces 24 and 29. The center- Y 'against the held or right-hand'follower 25,f

ing'of the left-band rocker20 automatically returns the right-hand rocker 2Ov to normal Y' position by means of the link 30.*V

When therockers 20 are lifted from the bearing plate 19, the same are supported by their pins 22 from the hooked ends ofthe link/ BO andv it is important to: note that said 'pins are located considerably above their centers of gravity, which materially assists in centering therockers 2.0. In actual construction, there will Abe sufficient play be-v .'"the rockers 2O are supported on the bearing platel19, Vto permit the tops of said rock- -ers to.l move out'of engagement withy the 'I bearing plate`14' when the rockers 2() areA lifted from the vbearing plate 19. Y The outp fwardly curved lower edge yof the housin .1 at'the endsthereof,aifords stops with l1 a theV rockers 2O engage to limit thei'rroc'k-l ing movement. 1 i f What I claim is I i ""1 1.
